From 9788864e2169ed3611e61c097efe4944c23fe7e9 Mon Sep 17 00:00:00 2001 From: Reinette Chatre Date: Wed, 6 Feb 2008 11:20:38 -0800 Subject: iwlwifi: do not clear GEO_CONFIGURED bit when calling _down The geos information is set up during probe and should only be removed during pci_remove, not during _down. This is a temporary fix until the setting of the status bits have been cleaned up (to explicitly match all setting with clearing of status bits).

If it is equal or above 8 we replenish the buffers. Ensure there is no starvation by initializing count to 8 - thus forcing replenish at first iteration.
